Moreno-Cruz Studies How Atlanta Residents Value MARTA

Primary tabs

Assistant Professor of Economics Juan Moreno-Cruz, along with colleagues in the School of Civil and Environmental Engineering, recently published a paper in Transportation Research.  The paper, titled “Do Atlanta residents value MARTA? Selecting an autoregressive model to recover willingness to pay,” was written with Gregory Macfarlane and Dr. Laurie Garrow, and is featured in Volume 78 of Transportation Research Part A: Policy and Practice.

Understanding homeowners’ marginal willingness-to-pay (MWTP) for proximity to public transportation infrastructure is important for planning and policy. Naïve estimates of MWTP, however, may be biased as a result of spatial dependence, spatial correlation, and/or spatially endogenous variables. In this paper, the authors discuss a class of spatial autoregressive models that control for these spatial effects, and apply them to sample data collected for the Atlanta, Georgia housing market. They provide evidence that a general-to-specific model selection methodology that relies on the generality of the spatial Durbin model (SDM) should be preferred to the classical specific-to-general methodology that begins with an assumption of no spatial effects. In addition, they show that applying the SDM raises the estimate of MWTP for transit proximity in Atlanta but also widens its confidence interval, relative to ordinary linear regression. This finding may have implications for risk estimations in land value capture forecasts and transportation policy decisions.  The full article can be read here.
